If you routinely measure large numbers of liquid samples the sipper accessory is most valuable. It consists of a 16 microliter illuminated volume flowcell and a peristaltic pump controlled by
the LS 55/50B Series software.

If using FURA 2 and BCECF, which are both excitation dyes, one drive unit (P/N L2250146) is required to fit on both pairs of filters. Both dyes can be monitored in the same experiment. If using INDO-1 and BCECF, two drive units are necessary- one for excitation and one for emission.

Consists of two filter wheels, each with horizontal and vertical polarizing films installed. The excitation and emission polarizer positions are software-controlled and can be independently set or automatically calculated for polarization, anisotropy or G-factor. Requires, but does not include, installation by a PerkinElmer Service Engineer.

Consists of two pairs of polarizing filters each set at 0° and90° to the vertical. Enables polarization values to be obtained every 40 msec. Requires at least two Drive Units (L2250146). Requires, but does not include, installation by a PerkinElmer Service Engineer.
